There are 12 radiators which I have sized using information of the Internet and had them checked by local plumber merchants. Heating requirement for rads is 19kW. We have one family bathroom that will have a separate shower cubicle, we also have an additional shower room but that will utilise an electric shower. The property was built in 1890s and is a mid terrace has four floors (or three and a cellar) There are two rooms in the cellar one used as an office the other as a utility room.
Plumbers merchant is suggesting a 35kw boiler and having looked at various models I am leaning toward the Viessmann Vitodens 100-W condensing combi. Previously we have had Vaillant boilers and never had any trouble with them.
I am now thinking of the controls system for the installation and would appreciate some advice.
